What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

JustDrones is a set of tunable fully chromatic virtual Uilleann bagpipes drones for intonation practice with any instrument. An optional additional just-tuned interval drone may be enabled a 3rd, 4th, or 5th scale tone above or a 5th or octave bass below the root. The volume of the main drones and the interval drone may be controlled independently. You may adjust the tuning of the main drones and the just-intonation based interval drone +/- 50 cents in one-cent increments using the fine-tuning slider control just below the drone puck. Touch the "Zero" button to quickly reset the fine tuning. Pitch selection, interval drone, fine tuning, and volume settings are saved when the app exits and restored the next time the app is run. The interval drones are tuned using just intonation relative to the drone root pitch for perfect consonance. Playing against drones is an excellent way to work on improving intonation. Tin whistle, wooden flute, and Irish fiddle players can all benefit from using the JustDrones as a practice aid. JustDrones can be enjoyed by anyone who wants to add the unique sound of the Uilleann pipes drones to their live or recorded music. Uilleann pipers, looking for an interesting alternative to standard D drones on a concert set? Set the main drone root to G and enable the 5th interval drone. To get even more usefulness out of JustDrones, try plugging your iPhone or iPod Touch into a set of external speakers. The drones sounds are from acoustic recordings without additional effects. Try connecting to external effects devices such as chorus or reverb boxes for even more interesting sounds. It also plays perfectly through the iPhone's speaker (make sure you turn off the ringer mute switch if you're not hearing anything). Please visit my website for demonstration videos of JustDrones and additional information.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
